Featuring a lightweight title fight between current champion Frankie Edgar and top challenger Gray Maynard, “UFC 125: Resolution” takes place Jan. 1 at the MGM Grand Garden Arena in Las Vegas, and the night’s main card airs on pay-per-view.

Brown vs. Nunes is scheduled for the evening’s preliminary card.

Brown, a 10-year pro who fought once for the UFC in 2004 as a lightweight, later joined the company’s sister promotion, the WEC. Brown won his first four fights in his new organization, which included a featherweight title win over Urijah Faber and title defenses over Leonard Garcia and Faber. However, he then lost his belt to current champion Jose Aldo.

Since then, the American Top Team fighter has posted a 2-1 mark with stoppage wins over Anthony Morrison (WEC 46) and Cole Province (WEC 51) and a KO loss to Manny Gamburyan (WEC 48).

Meanwhile, Nunes makes his UFC debut after posting a solid 4-1 mark in the WEC. Although the Brazilian and Nova Uniao team member entered the WEC with a 11-0 mark with 11 stoppage wins, all of his WEC victories (over Province, Rafael Dias, Raphael Assuncao and Tyler Toner) have come via decision. His lone setback came a year ago when he suffered a decision loss to L.C. Davis at WEC 44.
